anybody violates calendar in such a way that all years have 366 days.
I may be mistaken but isn’t ?merge function what you really want?

This idea substract 1 for the all column which is not what i want.
We know that the leap years have 366 days. I don't need to change anything
on them
the non-leap years have 365 days. This is what i want to change to be 366
days rather than 365 days.

Hi Lemon,
I am using the code you sent. It's correct for the leap years.
What I want to do is to have both leap and no-leap years to have 366 days.
that means the 1st March is day 61 of each year.
This will help me to link it with Instat for climatic data analysis.

The idea is that I want the non-leap years to be 366 days instead of being
365 days. ie. Each year must have 366 days.
for example: in the column Start2, Apr 18 will be Apr 17.

Thanks All. Your idea is useful!!!

Dear All,
How can I change the format of date of day of the year ? for example r
(i.e. "17 Apr" rather than "108").
The following is the type of the dataset I have

1 1930 108 288180

See ?as.Date. In your case, I think you should use
Hi,
If the dates are the same format and the same length you can try this :
dates<-c("1/1/2009","2/1/2009","3/1/2009")
dates_new<-as.Date(paste(substr(dates,1,3),substr(dates,7,8),sep="/"),format="%d/%m/%y"),
you can change the format to "%m/%d/%y"

Can you dput() your data frame? There are a different few time objects
in R and details might depend which one you have. Though, if it's
printing like that, I'd guess it's actually a string that you can
convert to a Date using as.Date(, format = XXX) where you can work out
the formatting from the d
